ILLINOIS, ASSIGNORS TO STANDARD CAR TRUCK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JnRsEY.

Application filed May 3, 1917.

To all whom t may concer/n.:

Be it known that we, FRANKLIN L. BAR- nnR and EDWIN W. WEBB, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Clar-Trucks; and we do hereby declare the following to beY a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in car trucks, and particularly to six wheeled equalized passenger car trucks. f

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and. dened in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views:

Referring to the drawings:

Figure 1 is a fragmentary plan View of the improved car truck; f

' Fig. 2is. a view partly in side elevation and partly in longitudinal central section; -Fig. 3 is a transverse vertical section taken on the irregular line 3-3 of Fig. 1;

Fig.4 is a detail view partly in elevation and partly in vertical section taken on the line 4.-4 of Fig. 1; and Y Fig. 5 is a detail view partly in elevation and partly in vertical section taken on the line 5-5 of Fig. 4f.

The 'truck frame, as shown, is made partly of cast steel and partly of rolled sections riveted together, ybut, as far as our present invention lis concerned, it may be cast entirely'in one piece. Each side frame of the improved car truck is indicated by the numeral6 and has rigidly bolted thereto, integrally formed pairs of pedestals 7. Between the members of each pair of pedestals 7 is mounted a journal box 8, with vfreedom for vertical movement. The lower ends of the several pedestals 7, ofeach side frame 6, are rigidly connected by a flat tiebar 9. These tie-bars 9 are laid in notches kformed in the lower ends of the pedestals 7 and riveted thereto. Outward of they outer pedestals 7, the tie-bars 9 are bent upward `and riveted to the side frames 6 and between the several pairs of pedestals 7, said -tie bars are twisted to turn the same on 'Specicaton of Letters Patent.

edge. The wheels and axles of the improved car truck are indicated by the numerals 10 and 11, respectively.

The two side frames 6 are rigidly connected by end members 12 riveted thereto. Said side frames 6 are further connected by four transoms 13 also riveted thereto, arranged in laterally spaced pairs and located between the outer and intermediate journal boxes 8. The outer of these transoms 13 are rigidly connected to the adjacent end members 12 of the truck frame by a pair of tie-bars 14 secured thereto by rivets and gusset plates. The two intermediate transoms 13 are rigidly connected by a pair of tie-bars 15- riveted thereto. For a purpose that will presently appear, the central portions of the intermediate transoms 13 are dropped and the tie-bars 15 are supported on these dropped portions and against the shoulders formed therein.

The members of a double truck bolster 16 are located, one member between each pair of transoms 13 and said members are rigidly connected by an H-shaped casting 17 bolted thereto and carrying a lcenter bearing plate 18. By reference to Fig. 2 it will be noted that the H-shaped casting 17 extends over the dropped portions of the intermediate transoms 13 and there is suiicient clearance therebetween to permit free vertical movement of the truck bolster 16. The ends of the members of the truck bolster 16 project under and outward of the side frames 6 and are further rigidly connected by side bearing arch bars 19 bolted thereto.

The double truck bolster 16 is indirectly supported from the truck frame by U-shaped hangers 21 and through which hangers the ends of said bolster' project.

These hangers 21 are suspended between the members of each pair of transons 13 by v[iat keys 22 and are located in the same vertical plane with the wheels 10 on the respective sides of the truck frame. The ends of the hangers 21 are mounted in bearings 23 and their intermediate portions extend through hubs 2tformed on the upper ends of the hangers 21. The keys 22 are turned edgewise and their upper and lower edge portions are rounded and it correspondingly formed seats in the bearings 23 and hubs 24. Obviously, the keys 22, owing to their transverse shape, are held .in the bearings 23 against turning movement and in turn hold thehangers 21 against swinging movement. The bearings 23 rest on the tops of the'transoms 13 and are riveted thereto. inserted into alined seats in the keys 21 and bearings 23, hold said keys against end- Wise displacement. By the use of the hangers 21 it is possible to eliminate the customary spring planks.

W'caring plates 26 for the truck bolster 16, which take the place-of the usualtruck columns, are mounted in channel-like seats 27 formed vertically through'the opposingfaces of each pair of transoms 13. Nut-equipped bolts V2S rigidly butl detachably secure the wearing plates, 26 to the transoms '13. Formed in the side Walls oflthe seats 27 are long vertical notches 29 which receive relatively short lugs 30von the Wearing plates 26 and assist in securing theysame in position in said seats. fIn the backs ofthe-Wearing plates 26 are verticalchannels 31 through which the vertical portions of the hangers 2l-extend. By means of `these channels 31 the'hangers 21 are further and securely held against swinging movement transversely of the car truck. rIlhe loiver end-s of the hangers 21 are co-ntracted and to afford p clearance therefor, ythe lower ends of fthe l displacement.

Wearing plates 26 are bifurcated.

The truck bolster l16 lis supported lfrom the hangers 21 and,\hence, from the "truck frame by elliptical springs 32 and lateral motion rollers 33. The springs 32 extend rtransversely, Withrespect to the truck frame,

and rest upon spring seat 34 in the form of castings mounted on thehorizontal portions oi the hangers 21. Laterally spaced lugs 35 on the ends of Jthe spring seat 3:4 engage opposite edge portions ofthe hangers 21 andihold said seats thereon againstlateral @n top of each elliptical spring 32is supported a roller base 36 having contours to receive therollers 33. T he truck bolster 16 rests directly upon thelateral motion rollers 33 and has formed vin `its under side contours 37 to receive said-rollers. `0n the ends of the roller bases 36 is -a' pair of laterally spaced guide 'lugs 3S arranged Ito receive the Wearing plates 26 and cooperate therewith to'hold said roller bases against lateral "displacement, but with freedom for vertical movement.

Stop lugs 39 on the sidesvof the truck bolster 16 are arranged to engageithe lWearing plate 26, under extreme lateral movement of the truck bolster 16'and limit said movement.

Equalizing-bars L10 have their outer ends supported on the outer journal boxes 8 and their inner ends supported on the intermediate 'journal boxes 8. These equalizing bars 40 are dropped, ybetween the journal boxes 8, linto substantially the same horizontal plane with the tie-bars 9 and arranged .sub-

Pins 25 o .Wearing plates afording stantially parallel therewith. The truck frame is supported from the equalizing bars 4.0 and hence from the 'journal boxesStby coiled springs 41. These springs'l are mounted on spring bases 42, supported on the equalizing bars 40 and their upper ends are `mounted in spring caps 13 ,integrally formed With the outer transoms 13 and located directly-under the side frames 6.

F rom the above description, it is evident that the load of the ear is directly on the doubletruck bolster and-it, in turn, is supported from the truck 'rameibyllateral-1no tion rbearing devices and elliptical springs.

rIhe Weight y on fthe Atruck frame 4is A applied to the journal `boxes tln'oughpthe coiled spring and equalizing bars.` -By the con- .struction and arr-angementor the vparts just referred to, each Wheel is allowedwto move vertically and independently `ot thevothers thereof.
